Ideas for rotating paint mixing shelf

[seanyb505]

In body shops I've seen vibrating shelves that can mix a large number of paints at once. This gave me an idea to build some mini version that would rotate, similar to a rotary tumbler. 

Last year I picked up a small charcoal grill that included an electric rotating spit, like this: Grill.

The mechanism comes off the grill and doesn't spin that quickly, maybe twice a minute. I'm wondering if this slow rotation would be enough to keep bottled paints properly mixed if left running overnight or for extended periods of time. Basically turn it on Friday night, do modeling on Saturday. 

I'd need to fashion some some of shelf and retaining system, but there doesn't seem to be many available options to draw inspiration from. Just vibrating vortex mixers that do a single bottle at a time and cost more than the free supplies I already happen to have on hand.

 I suppose the main issue would just be the slow speed. Whether I could speed it up by switching gears or not, is this a dumb idea to keep paints ready to use whenever I actually sit down to work?

That sounds like great idea.  I have considered something similar in the past. I don't think the slow speed is a problem as long as it keeps on moving.  I would think even slower (liek 1 or 0.5 rpms) would be ok.
